Specification of- Letters Patent.

Patented Aug. 11, 1914.,

Application filed March 7, 1914. Serial No. 823,249.

To all whom, it may concern: Be it known that I, JOHN TRISCHAN, a

subject of the Emperor of Austria-Hungary, residing in the city of Chicago; county of Cook, and State of Illinois, have invented certain new' and useful Improvements in Rubber Heels, of which the following is a specification. i

The object of my invention is to provide rubber heels of superior durability, considering the quantity of rubber used, and means for fastening rubber heels to shoes which are held; Fig. 4'is an enlarged detail section of the fastening means, separated, in juxtaposition to each other; and Fig. 5 is a partly sectional side view showing my heel 1n position.

Referring to the drawings, a rubber heel 10is provided on its lower surface with halfspherical warts 11, and on its upper surface with elongated central depression 12. Opposite 'towarts l'l-there are embedded in heel 10, at its upper surface, preferably split metallic sockets 13, ring flanges 14 of which lie flush with such upper surface While their pockets 15 are adjusted hold rounded heads 16 of nails 17, which are driven into the heelbase 18 of shoe 19, and which are preferably provided with disk flanges 20 which lie flush with the lower surface of base 18, limiting the enetration of nails 17 into base 18. Need e-openings 21 extend through the centers of warts 11 and Uopies of. this patent may be obtained for five cents each, by addressing the .surface directly below to receive and to pockets surface of base 18 the spots at which nails 16 are to be driven into such surface in order that they may be properly located with reference to sockets 13 around which rubberheel 10 is cast, and which therefore cannot be moved from the1r respective locations.

It will be observed that central .depression 12 saves rubber, and at the same time tends to promote all around contact of the upper edges of heel} of base 18, by obviatlng anycontact of these bodies near the center; also that warts 11, make it convenient the lower side of heel 10 for the purpose of inserting needle 22'; and finally that my cons truction does away with the driving of nails through the rubberheels' a I claim:

1. In rubberheels, the combination of,

split, metallic sockets arranged to engage the heads of nails driven into a heelbase, with a rubberheel cast around said sockets, said rubberheel and sockets having needle openings extending through the center of said sockets at ri ht angles to the treading surface of said eel, for the purpose described.

2. In rubberheels, the combination of, split, metallic sockets, arranged to engage the heads of nails driven into a heelbase', with a rubberheel ca'st having a semispherical wart on its treading each of said sockets and a needle opening extending through the center of each socket and wart, at right angles to the treading the purpose described.
